Description

technical field [0001] The invention relates to a capacitive coupling type non-contact power transmission device, which belongs to the technical field of electromechanical equipment. technical background [0002] In the type inspection of ship products, test items such as flushing, water spraying, and water pressure will be involved. Therefore, the test environment is often in a humid and watery state, and the power transmission interface of the electromechanical equipment working in this environment must be strictly waterproof. Only when it is sealed can it be used, otherwise leakage, short circuit and other phenomena will occur, causing damage to the equipment and even injury to the operator. The non-contact power transmission method can avoid direct contact between the power transmission interface circuit and the humid environment, and improve the safety and reliability of the equipment. However, the electromagnetic induction non-contact power transmission method commonl...

Problems solved by technology

This method needs to wind a coupling coil, and the AC resistance of the coil under high-frequency alternating current is much greater than the DC resistance, so the coil generates serious heat, which limits its current-carrying capacity and causes serious losses.

On the other hand, the alternating magnetic field will cause serious electromagnetic interference to the external environment
